The Gecko and Chuckwalla lizards are found in the southwestern United States. The Gecko lizard has an amazing ability to run upside down across the ceiling regardless of what the ceiling is made of and can run sideways across a wall, again regardless of the content of the wall. This has confounded scientists for some time. We have known for some time that the pads of the feet of the Gecko lizard are covered with little fine fibers, but this did not explain how the lizard could walk upside down on the ceiling.
Able to take pictures of the lizard’s toe pad magnified to 35,000 times, the electron microscope was able to reveal the answer. At the end of each of these fine fibers, there was a microscopic suction cup, each measuring eight-millionths of an inch in diameter. These suction cups allow the Gecko to run upside down on the ceiling and not fall off. These suction cups also present a challenge: how do they maintain suction and then release it so the little lizard can walk across the ceiling and not be forever stuck in the same place? His feet are specifically designed so that the tips of the toes bend or curl upward so that he can peel off the suction cups gradually at each step and not get so firmly stuck to the surface as to remain stuck.
Another very interesting lizard is the Chuckwalla lizard. The second-largest lizard species in the United States, its body shape is reflected in its scientific name, Sauromalus, which means flat lizard.
This lizard has skin across its back, almost like a blanket, and can change its colors throughout the day depending on its need for warmth. In the early morning, when it is cool, the lizard is dark-colored, allowing it to absorb heat from its surroundings. As the day warms up, the lizard changes to a light sandy color, allowing it to reflect heat and not burn up in the desert sun.
Another interesting design built into his body, allowing him to live in the desert, is a desalination (salt removal) factory in its nose! When the salt in his blood gets too high, the blood is shunted through this nasal factory, and the excess salt is removed. The lizard then sneezes out pure salt crystals, keeping the salt in its blood at levels compatible with life.
A third interesting fact about this lizard is its ability to protect itself from predators. When in danger, the lizard will run into the crevice of a rock and expand its body like a blowfish. Its body enlarges to perfectly match the crevice in the rock, and then it cannot be pulled from the crevice.
Evolutionists can find no fossil record that the feet of the Gecko evolved. So, it seems evident that they were perfectly formed to meet the needs of this little lizard. Neither can they find fossil evidence of the Chuckwalla adapting its life-saving mechanisms randomly and over time. These remarkable lizards clearly point to intelligent design by their Creator and not evolution.
